Which method could be used to obtain copper from a mixture of powdered copper and sodium chloride?
Electrolysis can be used to separate copper from a mixture of powdered copper and sodium chloride. By passing an electric current through the mixture, the copper ions will be attracted to the negative electrode (cathode) where they will be reduced and deposited as solid copper. This process will allow the separation of copper from the sodium chloride.
Copper reacts with sodium hydroxide?
Copper metal itself does not react with sodium hydroxide. But when NaOH is added to a solution of copper ions, it would form a light blue precipitate, which is copper(II) hydroxide, and will NOT dissolve with the excess alkali.
Does sodium oxide dissolve in water?
Yes, sodium oxide (Na2O) does dissolve in water. When sodium oxide reacts with water, it forms sodium hydroxide (NaOH), which is a strong base.
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
Is there a limit to the amount of sodium chloride that will dissolve in 30 grams of water?
Yes, there is a limit to the amount of sodium chloride that can dissolve in 30 grams of water. This limit is known as the solubility of sodium chloride in water. At room temperature, approximately 36 grams of sodium chloride can dissolve in 100 grams of water.
Do metals dissolve in water?
Most metals (like Steel, Aluminium, Copper etc.) do not dissolve in water, however there are some (like Sodium) that will.
Which will dissolve in water Air Sulfur or Copper?
Sulfur will dissolve in water, while copper will not. Copper is insoluble in water.
Does sodium dissolve in water?
Yes, sodium dissolves in water.
What will dissolve in water copper electrode and silver electrode?
Copper electrode will dissolve in water to form copper ions, while silver electrode will not dissolve in water as silver is relatively unreactive. Copper ions will be present in the water solution after dissolving the copper electrode.
How do you obtain copper from a mixture of powered copper and sodium chloride?
Put the mixture in a beaker then add some water. Stir until the sodium chloride is completely dissolved. Filter the water to get copper oxide as your residue. Then strongly heat the water till it evaporates, to form crystals of sodium chloride.
What does sodium dissolve in?
water
How does water dissolve sodium?
Water doesn't dissolve sodium, water react violently with sodium:2 Na + 2 H2O = 2 NaOH + H2

How do you dissolve copper sulfate and water?
To dissolve copper sulfate in water, simply add the copper sulfate powder to the water while stirring continuously. The copper sulfate will dissolve in the water to form a clear blue solution. Be cautious when handling copper sulfate as it can be harmful if ingested or inhaled.
